SPECIFICATION forming part of Letters Patent No. 778,217, dated December 27, 1904; Application filed March 29, 1904. Serial No. 200,537.

To al@ whom it myconcern:

Beit known that I, EDWARD G. BUDD, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Cushions for Car-Seats, of which the following is a specification.

My invention has reference to cushions f or car-seats; and it consists of certain improvements which are fully set forth in thefollowing specification and shown in the accompany- -ing drawings, which forrn a part thereof.

The object of my invention is to provide a construction for cushion frame adapted t0 both seat and back which shall be composed largely of metal and be substantially lireproof.

My invention is especially adaptedV for use in the railway-car seats, vwhere the danger to loss of life from fire is very great in case of collision. I

In carrying out my invention I employ an outer or boX frame of metal, preferably Shaped Yin cross-section and bent into the requisite rectangular form, and combine therewith sheet-metal bands arched overthe top from side to side, `Coil springs under said steel bands, transverse metallic slatsor crossbars supporting said springs and united at their ends to the side portions of the outer frame by bolts, and a covering of woven ratan or other upholstery the free edges of which are folded under the outer frame and united thereto by eyelets and preferably shielded by metallic strips which impart both protection and finish and through which the eyelets extend. y

My improvements also comprehend details of construction, which, r together with the above-mentioned structures, will be better understood by reference to the drawings, in which- Figure lis an inverted plan view of my improved seat with a portion ofthe slats and springs broken away to show the interior. Fig. 2 is a cross-section of same on line A A. Fig. 3 is a cross-section of same on line B B, and Fig. 4: is an inverted plan view showing the employment of protecting-strips over the upholstery.

The box-frame is rectangular andv made of rolled sheet metal of substantially I: shape in cross-section, the outer wall a having the top flange a' and bottomflange a2. vThe free edges of these-flanges may be curved, folded, or beaded, as shown at ai, which adds greatly to the strength. The two longest sides of the box-frame have their upper outer surfaces depressed, as a3, to receive the ends of the springs and rivets b. I prefer to make the box-frame of one continuous strip of sheet metal, with the parts e and e2 cut so as to form miter-joints at the corners.

b .represents fiat springs arched over the upper or Vouter surface of the box-frame and are seated at their ends upon the opposite side rails and riveted at 1)', as before stated. These vspring-plates are preferably provided upon their under sides with a central strip 62 of greater strength and to both of whichplates the coil-springs Z are bolted. The lower ends of these springs are supported upon transverse bars or slats e, formed of stamped sheetsteel and ribbed, as at e', for rigidity. These ribs do not extend to the ends ofthe slats,

but instead terminate a short distance from eachend, and said ends are fitted against the under surface of the flange a2 0f the box-frame and secured in place by bolts/0. vIn practice I prefer to have the springplates come close together, so as to form only a small space between them to insure the structure being more iireproof.

Above the spring-plates b is placed the upholstery, and ordinarily this consists of a sheet of canvas c and a covering of woven ratan 0 or other outer material. This upholstery may be of any other construction .preferred and may be made reproof in any of the wellknown ways. The upholstery is pulled down over theAboX-frame and folded under the bottom lange a2 and held Vin place by the screws 7c and eyelets or rivets c'. If desired, before the eyelets are applied protecting-strips /L are placed over the upholstery ends and preferably under the slats c, and-said strips, the upholstery, and the iiange co2 are further fastened together by the eyelets t', as shown in Fig. 4, the eyelets passing through holes in the several parts. The eyelet-holes in the iiange c2 are shown at t in Fig. 3.

From the foregoing description it will be seen that the cushion is essentially fireproof and at the same time both light and strong.

Matter shown but not claimed in this application forms subject matter of another pending application, Serial No. 186,609, and liled December 26, 1903.

While I prefer the construction herein shown and described, I do not confine myselil to the details, as these may be modified without departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is.-

l. In a seat-cushion, the combination of a box frame of sheet metal having bottom iianges, cross-slats of metal having their ends resting against the bottom face of the bottom iianges of the box-i`rame, coil-springs resting upon the slats, sheet-metal springs resting upon the coiled springs and having their ends secured to the sides of the box-frame, upholstery stretched over the sheet-metal springs and extended down and under upon the lower flange of the box-frame, means passing through the ends of the cross-slats upholstery and ange of the box-frame to hold them together, and means for securing the upholstery to the iiange of the box-frame intermediate of the slats.

2. In a seat-cushion, the combination of a box frame of sheet metal having bottom anges, cross-slats of metal having their ends resting against the bottom face of the bottom iianges of the bex-frame, coil-springs resting upon the slats, sheet-metal springs resting upon the coiled springs and having their ends secured to the sides of the boxiirame, upholstery stretched over the sheet-metal springs and extended down and under upon the lower flange ofthe box-frame, means passing through the ends of the cross-slats upholstery and ange of the box-frame to hold them together, and means consisting of eyelets for securing the upholstery to the flange of the box-frame intermediate of the slats.

3. In a seat-cushion, the combination of a box frame of sheet metal having bottom iianges, cross-slats of metal having their ends resting against the bottom iaee ol the bottom ianges of the box-frame, coil-springs resting upon the slats, sheet-metal springs resting upon the coiled springs and having their ends secured to the sides of the box-frame, upholstery stretched over the sheet-metal springs and extended down and under upon the lower iiange of the box-frame, means passin gthrou gh the ends oi'l the cross-slats upholstery and iiangc of the box-frame to hold them together, protecting-strips o12 metal covering the upholstery edge, and eyelets extending through the protecting-strips for securing the upholstery to the flange oi' the box-trame intermediate ol the slats.

4. A seat-cushion for cars consisting ol a box-frame of sheet metal having a lower flange, upholstery7 extending over the hexframe and under the lower liange, springs l'or supporting the upholstery, metal cross-slats for supporting the springs having their ends extended over the upholstery and resting helow the lower iiange, means for securing' the cross-slats to the iiange and clamp the npholstery, and means for riveting the upholstery to the lower iiauge ot' the boxslrame intermediate of the slats.

5. A seat-cushion for cars consisting' ol` a box frame ot' sheet metal having ay lower iiange, upholstery extending over the box- Jframe and under the lower flange, springs lor supporting the upholstery, metal cross-slats for supporting the springs haring their ends extending over the upholstery and resting helow the lower iiange, means for securing the cross-slats to the liange and clamp the upholstery, means for riveting the upholstery to the lower flange oi the boxftrame intermediate ol the slats, and protecting-strips of metal over the upholstery and also secured in place by the riveting means.

In testimony oli' which invention I hereunto set my hand.
